Everything you need for a flexible application core in one unified platform
In the race to bring cloud software to market, developers are forced to hack together the core of your application with fragile custom code that hobbles your business as you scale. With Chassi, you can easily modify customer lifecycles, subscription plans, feature-level access control, and pricing offers with full visibility into your customers—without custom code.
Old Way
Custom code that limits business flexibility
New business requirements to change pricing, test product offers, or measure customer engagement never seem to make it to your roadmap. Your feature code is bound to your product definition, making it fragile and inflexible.
Customer success exists outside your application
Lack of visibility into specific customer lifecycles leads to excessive churn, poor satisfaction, and lost business opportunities. There’s more to customer success in your app than a credentialed account and a subscription.
No way to test product and pricing offers
You have no way to easily test multiple product bundles, promotional offers, or pricing strategies. The dirty secret is software businesses are not agile and your business isn’t growing as fast as it could.
Wasting time on application plumbing
You are spending valuable roadmap time building and maintaining custom core application code while you could be working on the highest-value features that drive your business.
New Way
Move as fast as your business requirements
Modify and implement in minutes without custom code. Launch and iterate faster. Minimize technical debt. Get visibility to know what’s working.
Build customer success into your application
Get detailed analytics on the performance of every customer’s journey through any lifecycle. Triggers help you proactively respond to customer issues to increase usage, retention, and sales.
Increase roadmap velocity
Stop messing around with app core plumbing and focus on the unique code that adds the most value for your customers. Remain agile with reactive programming systems that significantly reduce development efforts.
Start fast and never outgrow it
Chassi helps you build customer-ready applications on Day 1 with the ability to scale infinitely. Use the languages, hosting, services, and components you already rely on.

Built for developers
Chassi is built for developers who love creating custom-built applications. The key to your success is reducing the amount of code necessary for you to realize the value of a customer-ready application, even in your MVP. Chassi lets you focus your time on your intellectual property, while providing a robust, enterprise-grade core to support your customers from Day 1.

Our APIs are powerful, comprehensive, and well-designed. We’re confident you’ll find them a pleasure to work with.

Webhook & Queue
Most web apps offer only webhooks and rarely allow you to directly connect with a queue. Chassi lets you send requests over the queue, and subscribe to our queue to receive messages, in addition to using webhooks.

App Spaces
Chassi provides you with an unlimited number of app spaces to model your SDLC, so you can create instances like dev, test, stage, and production for any number of team-specific dev environments.

Data Lake Access
Chassi gives you raw access to 100% of your data through a data lake. Connect any RDMS client or analytics tool to your raw data source so you can perform whatever activities you wish to help you better understand your customers.

Code Libraries
Each of our APIs have client libraries pre-built to handle our extensive data transfer objects, so you can easily marshall data between your app and our APIs. Libraries are available in a variety of languages, so you can quickly realize the value of the APIs.

Starter Apps
Starter applications will be available soon to help you springboard your new application to market faster. These starter apps give you robust templates to build on, allowing you to focus on your intellectual property immediately.

Chassi has extensive API documentation, code library documentation and end user guides. We work hard to make sure that our product is well documented, including screencasts for every feature.

Chassi is both PCI-compliant and HIPAA-compliant. We will sign necessary BAA agreements for the healthcare space. Our APIs feature a Zero-Trust security architecture with end-to-end encryption, both in transit and at rest.
